Separate hover ceiling charts are provided for rotorcraft equipped with either the
inlet particle separator (IPS) or screen inlet and heater operation.
The phrase, ``A/C On'' only is applicable to the MDHI air‐conditioning installation
PN 900P7250302-101.
NOTE
:
The charts are based on an electrical load of 15% per generator (30 amps per
generator). Reduce/increase gross weight capability by 35 lb (16 kg) for each
10% increase/decrease in total load.
For many operations, a reduction in gross weight capability still allows the
rotorcraft to operate at a maximum gross weight of 6500 lb (2948 kg). Follow the
example shown below:
Use of Chart:
The following example explains the correct use of the IGE Chart
Example:
Wanted: Maximum gross weight for hover at 3.5 feet skid height at takeoff power.
Known: PA = 7000 feet; OAT = 30
°
C; cabin heat off and A/C on; 25% electrical
load.
Method: Enter the chart at 30
°
C OAT and move vertically to the 7000-foot PA
curve (dashed lines). At this point, move directly to the left of the chart
and read from the gross weight scale 6280 lb.
Gross weight data above 6770 LB has been provided for calculation
purposes or external load operations only. Weights above 6770
LB must be external and jettisonable.
The instructions for the IGE hover ceiling charts also are applicable to the OGE
hover ceiling charts.
